Fraser Valley Home Maintenance Guide
A thorough seasonal checklist for Abbotsford, Langley, Mission, Chilliwack & surrounding areas
The Fraser Valley’s mix of heavy rain, moss growth, windstorms, damp winters, and warm/dry summer stretches is tough on homes. A simple, consistent maintenance routine can prevent the most common (and expensive) issues: moisture intrusion, rot, mold, roof leaks, and drainage problems.
Below is a more thorough, practical checklist you can post as a blog and homeowners can actually use.
The “Always” Monthly Quick Check (10–15 minutes)
These are fast checks that catch problems early:
Walk the perimeter after heavy rain: look for puddling near the foundation, downspouts overflowing, or splashback staining.
Look up at the roof from the ground: missing shingles, lifted edges, sagging gutters, debris in valleys.
Check for new interior water marks: ceilings under bathrooms, around skylights, near exterior walls.
Run bathroom fans during showers and confirm they’re exhausting well (hold a single sheet of tissue up—should stick).
Peek under sinks for slow leaks and damp cabinet bottoms.
Test GFCI outlets (kitchen, bath, exterior) using the test button.
Spring Maintenance (March–May)
Spring is your “reset” after winter moisture.
Exterior & Drainage
Clean gutters and downspouts (and check the gutter slope).
Confirm downspouts discharge 6+ feet away from the home (use extensions if needed).
Check that the yard slopes away from the foundation (no negative grading).
Clear and test area drains / catch basins (if present).
Inspect retaining walls for leaning, bulging, or new cracking.
Roof & Chimneys
Look for:
cracked or missing shingles
exposed nails
damaged flashing at chimneys/vents
debris in roof valleys
Check chimney crown for cracks and masonry for loose mortar.
Siding / Trim / Windows
Inspect wood trim and siding for:
soft spots (early rot)
peeling paint
open joints or failed caulking
Re-caulk small failed areas (don’t seal weep holes).
Interior / Moisture
Check attic access areas for:
damp insulation
staining on roof sheathing
musty smells
Check basement/crawlspace for:
dampness
efflorescence (white powder on concrete)
musty odours
Mechanical
Replace/clean furnace filter.
If you have a heat pump: clear debris around the outdoor unit and ensure good airflow.
Summer Maintenance (June–August)
Summer is the best time to repair and protect.
Exterior Repairs & Protection
Repaint/seal exposed wood (fascia, trim, decks, railings).
Inspect and seal cracks in:
walkways
patios
driveway areas that channel water toward the home
Roof & Moss Control
If moss is present: consider professional moss treatment (avoid pressure washing shingles).
Trim tree branches back from the roof to reduce debris and shade.
Decks, Stairs, and Railings (Safety)
Check:
soft/rotted boards
wobbly railings
loose stairs
ledger attachment points (where deck meets house)
Re-stain or seal as needed.
Plumbing & Water
Inspect hose bibs for drips.
Check visible plumbing for corrosion or mineral deposits.
If you have a sump pump: test it and consider a backup.
Electrical
Ensure exterior outlets have working in-use covers.
Look for damaged exterior wiring, lights, or loose fixtures.
Fall Maintenance (September–November)
Fall is about preparing for rain + wind.
Rain Readiness (Biggest Fraser Valley priority)
Clean gutters again once leaves start falling.
Confirm downspout extensions are attached and draining properly.
Clear roof valleys and check for debris buildup.
Check grading and patio drains—water should not run toward the home.
Heating & Indoor Air
Service furnace/heat pump if due.
Replace filters.
Test smoke + CO alarms.
Confirm bathroom fans and kitchen exhaust are working properly.
Attic & Ventilation
Make sure soffit vents are not blocked by insulation.
Look for signs of condensation in attic spaces (staining, dampness).
Windows & Doors
Check weatherstripping and door sweeps.
Lubricate window tracks and ensure they lock properly.
Watch for condensation patterns as temperatures drop.
Winter Maintenance (December–February)
Winter is mainly about preventing moisture damage and freeze issues.
Freeze Prevention
Disconnect hoses and shut off exterior taps (if you have an interior shutoff).
Insulate exposed pipes in cold areas (crawlspace/garage).
Know where your main water shutoff is.
Moisture Control Indoors
Keep indoor humidity reasonable:
run bath fans
use range hood when cooking
Watch for:
heavy window condensation
mold at window corners
musty odours
Storm Checks | After windstorms or heavy rain:
Walk the perimeter for:
overflowing gutters
downspouts disconnected
water pooling
Look in attic access areas for new staining.
Fraser Valley “High-Value” Maintenance Items (Most Worth It)
If homeowners only do a few things, these have the biggest payoff:
Gutters + downspouts kept clear
Downspouts discharge away from the foundation
Roof debris/moss managed
Bathroom fans vent properly + used regularly
Attic ventilation/insulation kept effective
Deck and exterior wood protected (paint/seal)
